Aug 30, 2019 Ball loading capacity The volume of the grinding medium is the percentage of the effective volume of the mill, which is called the filling rate of the grinding medium. The size of filling directly affects the number of shocks, the area of grinding and the load of grinding medium in the grinding process.
May 01, 2020 The average grinding rate of the 6.0 mm sized particles increased with an increase in the size of the ball medium from 0.316055 of 80 mm to 0.474508 of 100 mm. Considering that the maximum size of the medium of the ball mill in the concentrator was 89 mm, the parameter k of the grinding kinetic equation for 100 mm was the largest and ...
Capacity. 1-95th. Input size. 25mm. Ball mill is a type of grinder machine which uses steel ball as grinding medium, can crush and grind the materials to 35 mesh or finer, adopted in open or close circuit. The feed materials can be dry or wet, they are broken by the force of impact and attrition that created by the different sized balls.
Advantages of this ball grinding mill include less friction, less energy and more easily activated, because large diameter double row self-aligning roller bearing instead of sliding bearing is used as the main bearing. This ball grinding mill can achieve bigger capacity thanks to
